   I think this is an interesting idea. It would be great to have a basic implementation as a starting point to see how best this could be handled and what APIs (if any) it might break.

   Since Axes.bar does not currently support arrays of strings for the first argument, this would be strictly new functionality and hence should not break any existing APIs.

   My thinking was to simply add a few lines to bar() in _axes.py that do something like:

   if all(isinstance(s, str) for s in left):
       labels = left
       left = range(1, len(left)+1)
       align = 'center'
   else:
       labels = None
   

   and then further below in the bar() function do something like

   if labels != None:
       if orientation == 'horizontal':
           self.xaxis.set_ticks(left)
           self.xaxis.set_ticklabels(labels)
       else:
           self.yaxis.set_ticks(left)
           self.yaxis.set_ticklabels(labels)
   

   (Though I'm not much of a Python hacker. I mainly use matplotlib from the Julia via the PyPlot.jl package.)
